HOOKERIACEAE. 285 
(Note.—The upper cells, as in Distichophyllum, are usually mark- 
edly smaller towards margin, and rapidly become much enlarged 
lower down the leaf, so that the com ar ison of the cell paamiue 
epends for its v alue on the same position being selected. I hav 
given measurements of the median cells well below the apex, but aa 
far down, at say one-fifth to one-fourth down the leaf).

A smaller species than the two following, usually in dense, tomen- 
tose tufts, and it would seem less frequently fruiting. It is recognized 
at once by the very stout, cartilaginous border, which is entire or 
slightly denticulate only; by the very stout, acute, cuspidate point, 
ne absence of nerve, and the size of the cells, which are isodiametric 
n £. cristatus, but much smaller, about 25- 35h In diameter, as 
eciliianel with 50- 604. The fruit, when present, moreover, is quite 
distinct, the seta being only lowly ‘papillose, smooth above. 
Distichophyllum platyloma C.M., of which I have seen the type, 
is certainly EZ. apiculatus, a slightly undeveloped form. The cells and 
general structure agree, but the border is more denticulate than usual. 
E. apiculatus is a rare species in N.Z., oceurring also in Tasmania, 
Eastern Australia, Fuegia and Chile.

A fine species, resembling in habit ita veer dentatum var. 
robustum, having stems as much as 10 em. in height, and 5 mm. or 
gees to — it from EF. flexicollis. The leaves are large, 
4-5 more, a in size and shape, the lateral often 
chlcsie sat httates the dorsal more rounded; they are of a thick tex- 
ture, and when dry are as shot crinkled at the edges. The 
nerve usually has the longer branch reaching quite to one-third the 
length of the leaf, or even higher, but is often very short. The cells 
are very large, and are regularly hexagonal above, and isodiametrie ; 
and being very pellucid and the thickness of the leaf quite appreci- 
able, they often show the lateral walls under a high power very dis- 
tinctly, so that the effect is exactly that of i into shallow cells 
of honeycomb. The border is distinct, of 2-3 rows of elongated cells, 
inerassate, but not as in E. apt iculatus, so that the border is green,
